INHALER.

SPECIFICATION formingY part of Letters Patent No. 529,808, dated November 2'?, 1894.

Application filed July 26, 1894. Serial No. 518,662. (No model.)

To all whom it may concern:

Be it known that I, SoLoN D. Ross, a citizen of the United States, residing at Manhattan, in the county of Rileyand State of Kansas, have invented a new and useful Improvement in Inhalers, of which the following is a specification.

My invention relates to an improvement in i that class of devices for administering volatile medicines to the internal or external surfaces of the body, in which the medicine is inclosed in a hollow shell, and is subjected to a current of air which is conducted to the surface it is desired to treat.

The object of my improvement is to provide improved means for holding the medicine within the shell.

The accompanying drawings illustrate my invention.

Figure 1 represents, on an exaggerated scale, a central vertical section of one form of my device. Fig. 2 represents a similar section showing a modified form of the medicine holder. Fig. 3 represents a perspective view of the medicine holder; and Fig. 4. represents a perspective view of the corrugated jacket used in the modified form of the medicine holder.

In the drawings, 2, indicates a hollow metallic shell, tapering in form, having its broader end uppermost, and formed, preferably, by spinning from sheet metal. Secured tothe smaller end of shell 2, is a cupshaped base, 3, also spun from sheet metal. The larger end of shell 2 is closed by a hollow cap, 4, having a central tubular extension, 5, which is closed by a screw-plug, 6. The smaller end of shell 2 is closed by a screwplug, 7. Mounted within shell 2, so as to leave a hollow space at each end, is the medicine holder, which consists of a central tubular standard, 8, having, secured .to its opposite ends a pair of thin perforated plates, 9, and 10. Said plates are of such size as to t nicely between the walls of the shell so as to sustain the holder in a suspended position between the ends of the shell, and the upper plate being removably secured to the upper end of the standard for convenience in placing the medicated packing.

In the form shown in Fig. l, the space between the plates, 9, and l0, and between the central standard, 8, and the walls of the shell, is filled with an absorbent material, l1, as cotton, which is saturated with a volatile medicine. Secured to the upper part of plate 9, is a swinging cover, l2,` by means of which the opening in the tubular standard may be.

closed.

In the modied form shown in Fig. 2, a tapering cylinder, 14, having longitudinal corrugations, and formed of thin perforated sheet metal, is arranged so as to connect the outer edges of plates 9 and IO, thus forming an inclosed package which maybe filled with medicine in a crystallized, or powdered form, and then inserted in the shell.

In operation, when it is desired to apply the fumes of the medicine toexternal surfaces, screw-plugs, 6 and 7, are removed, and the open cup-shaped base is placed over the surface which it is desired to treat. The fumes from the medicine pass, either by a naturalv the body, as the internal ear, a rubber tube,

(not shown,) terminating in a suitable nozzle, is secured to the extension 5, and air is forced through the device by applying the mouth to the open end of the base 3. When but slight medication of the air passing through the device is required, the central standard 8, is left open, but when a more thorough medication of the airis required, the opening in said standard is closed by means of the cover l2, thus compelling a circulation through the perforated plates 9, and l0, and the medicine inclosed between them. When cylinder 14. is used, the opening in the central standard being closed, the circulation passes not only through the perforated plates 9 and 10, but along the oorrugations and rated plates secured to its opposite ends, of xo through the perforations of said cylinder, the swinging Yalye piyoted to one'of said thus compelling a more complete and thor'- pletesand adapted to elosethe opening in the ough impregnation of the aiiwth the fumes standard, as set forth. 5 of the medicine.

I claim as my invention- SOLON D ROSS' In an inhaler, the combination with the Witnesses: shell and the medicine holderl consisting of a EDWARD L. KUASTMAN, hollow central standard and a pair of perfo- CHARLES W. KIMBALL.
